代码
return JsonResponse({"name": "tom"})
报错:
TYPEERROR: In order to allow non-dict objects to be serialized
set the safe parmeter to False
解决:
return JsonResponse({"name": "tom"}, safe=False)
增加safe=false,使其接受列表
补充知识:python 里面 JsonResponse (book_list,safe=False)
代码为:

遇到问题:
JsonResponse (book_list,safe=False)
safe=False 这是什么鬼 ?
解决方案:

if safe and not isinstance (data, dict ): raise TypeError( 'In order to allow non-dict objects to be serialized set the ' 'safe parameter to False.' ) if json_dumps_params is None : json_dumps_params = {} kwargs.setdefault( 'content_type' , 'application/json' ) data = json.dumps(data, cls = encoder, * * json_dumps_params) super (JsonResponse, self ).__init__(content = data, * * kwargs) |
最终答案:
'In order to allow non-dict objects to be serialized set the ' 'safe parameter to False.'
